Silver NHC catalysts have been developed for the selective oxidation of alcohols to aldehydes or carboxylic acids in the presence of BnMe3NOH or KOH under dry air. The aerobic oxidation conditions are mild, and the yield is excellent. Further tandem catalysis enables the one-pot synthesis of imines in excellent yield. Only 0.1 mol % of the catalyst is required.
General, Green, and Scalable Synthesis of Imines from Alcohols and Amines by a Mild and Efficient Copper-Catalyzed Aerobic Oxidative Reaction in Open Air at Room Temperature
A general, green, and scalablesynthesis of the useful imines and α,β-unsaturated imines is successfully achieved by a low-loading and powerful, mild and efficientcopper-catalyzedaerobicoxidativereaction of alcohols and amines in the openair at roomtemperature under base- and dehydrating reagent-free conditions. This practical reaction can use air as the economic and green oxidant, tolerates
